Ok so this is driving me absolutely nuts, got a 2015 Adam 1L Turbo with the Start/Stop eco mode. I appreciate that I can turn it off each time I get in, but is there any way to disable it permanently? I didn't buy the car to be an eco warrior and drive it carefully to save fuel, I bought it to drive.

I get the whole eco thing and for some people's driving style it might just work; for mine it most certainly doesn't and is driving me insane. Come to set off and car won't move because its busy starting its self back up, or letting up the clutch ready to set off and car stalls because it hasn't finished starting. I'd say sometimes its down right dangerous and as the driver I should have the option to turn this off.

Does anyone know of a way to disable this other than drastic measures?

According to the manual you can turn the stop / start system off by pressing the Eco button , once the LED has gone out stop/start is off . I'm guessing you've got to remember to press the button each time you fire the engine up? If so its no different to the system that VW use on say the Passat , i had to remember each time to turn it off upon restarting the engine .

That's correct, I can press the "Eco" button each and every time I get in the car but I don't want to have to do that, I want it to be off by default and if I require I can turn it on. If there is no "official" solution then I will continue down the track I am heading and find a hack to make it operate in the manner I wish.

I'm thinking something like the attached with maybe a few capacitor changes to alter the timings.

As far as I know, apart from turning it off by the eco button, like mine. There's no way to prog it out at vaux.
Are any of the Adam 1.0t none s/s?
Unlike yourself, I like the s/s function. Suits my driving style, type of town driving I'm encountering. I've only switched mine off around 3 times in the last 6 months.
S/s not good in rolling traffic.

I've driven Fords with the stop start and they don't seem to be too bad. It's maybe just Vaux implementation of it. Seems very laggy for want of a better word, and just doesn't respond quick enough when I decide I want to go. If I do go down the hack route I'll happily post pics along the way with explanation.

Had to do a similar thing to my old Rav 4 that Toyota saw fit to put electric mirrors on but you had to manually press a button to fold them in. I 'tweaked' it so they came in and out automatically as I started and stopped the ignition.

Mine is not 'laggy' on my 63 Astra 2.0cdti. This is my first ss car. It fires up very quickly. I've had it cut out, fire back up within a second. Very quick to fire up, to move away.

Not sure what would happen as your cars on the can bus system & like Boroboy says I'm not sure you could program it out. There is a lot of criteria parameters involved in the functioning of the stop / start system , does yours have the autostop system fitted ?

It's definitely got it fitted, and it will definitely be disabled very shortly. :)

I was hoping for a less intrusive method, but if it requires a hard mod then so be it.

Thanks for the replies and info so far.

There must be an easy way to disable it. As you say Fred the S/S system uses a lot of different sensors and to be able to function correctly. It would only take one of those sensors to become "faulty" for the S/S not to function.

Bonet switch sounds like the easiest of the triggers to break, but I guess that's a reasonable safety feature.

Easiest way would be for the battery not hold a sufficient capacity of charge say instead of not meeting the criteria of approximately 77% & above dip slightly below that figure & the stop / start would no longer function.

How would you fake the battery charge?

The only other sensor I could think that might do the trick without triggering a light on the dash would be the clutch. Question is would it have any adverse effects?

Like I said I'm not averse to making a small modification circuit to sit behind the Eco button. I just can't believe Vauhall made it so hard to permanently turn off.

I wouldn't muck about with clutch sensor the ECU uses that information along with the brake switch . I think the reason you can't permanently disable the stop/start is because it's fitted to be used not permanently ignored , i personally don't like it myself as it's very complex & frustrating as a driver , i just want to get in & drive feeling relaxed & rolling up to junctions not having to worry if the engines gonna cut out & not start again. The passat bluemotion I had drove me mad , stop/start plus electronic handbrake , every time you opened a door the system would reset back into lock/braked mode , so putting your clutch down , selecting gear & releasing handbrake & pressing throttle did nothing , car would refuse to budge , "WTF" press brake pedal then system would let you start all over again , clutch down , gear selected , electronic parking brake released , throttle pedal pressed & away !!!!

Vaux got rid of the elec handbrake on the Astra J. I've not used s/s with an elec handbrake. Found the elec handbrake more tiresome on hill starts. There's also HSA now, which I like, but takes a bit of getting used to.
Regarding s/s, just a case of switching it off, if you don't want to use it. I'm one of the lucky ones, get along with it. Find it easy to use. Mine tends not to work on dull wet mornings.

Thanks for the replies guys, and its as I suspected, I was reluctant to start messing with sensors etc anyway.
So I will continue down the route of a button hack to simulate a press once I have started the engine.

The new audrino is out its $9 and the size if a key, if you google and ask about you could probably get someone to write some code and mod it to the button so when it receives power it the code makes it trick the button into thinking its been pressed. I cant imagine the button is anything more than a momentary switch.

Josh, thanks for the info, I'm a Software Engineer so could possibly sort out my own Arduino out. I decided to go with things I might have in the house and as it happens I've managed to put a circuit together completely from old parts I had lying around. This is more by good luck than judgment as I didn't look for the parts until I had a working design. I said I would share it so here it is ...

Find attached: Circuit Diagram, Breadboard Layout in the online Simulator, and the "real" circuit I made from the spare parts.

I'll admit this is the first circuit I've designed, or better yet attempted to build in about 15 years so you can imagine my surprise when it worked almost perfectly first time.

Simplistically its a 2 stage circuit, the first is a delay of about 8 seconds, followed by a single pulse on the relay of around 1/2 a second. This allows me to power up the circuit while starting the car, then about 5 seconds after the engine is running and its all settled down the relay simulates a button press of the pesky "Eco Button" which turns it off each and every time I start the car. (Note: as the circuit powers up there is a single 1/2 second pulse on the relay, due to the circuit powering on, however this is simply ignored by the car, hence the need for the delay after ignition and another pulse which is the real trigger.)

As you can see from the bread board simulator, at rest after the circuit has performed its duties it draws a nominal 2.69 mA. The Circuit Diagram and the Breadboard pic show an LED and resistor over the relay, this was just for testing. You would connect the normally open points of the relay in parallel with the Eco Button. I did it this way so as not to interfere with any sensors or other safety features in the car, also makes it easy to remove should the need arise.

I haven't got it installed yet so I guess its all still theory, but I will post some more pictures and maybe a quick video once I have it in and working!

Kind Regards

Thanks for posting Info.
Friend owns a ford ka, when he turns off the s/s button on his dash. The s/s stays off until he manually turns it back on. Even after restarting the car. That sounds sensible. Can't understand why vaux didn't adopt the same idea? Lol
